WEATHER STRIP David G. Bailey, Amesbury, Mass.

Original application January 18, 1939, Serial No. 251,544, nowPatcnt.No. 2,197,332, dated April Divided and this application Novemher9, 1939, Serial No. 303,649

Claims. This invention relates to certain improvements in weatherstrips, or window glass guiding and cushioning means, which areprimarily intended for use in the construction of automobile bodies,'

and is a division of my application filed January 18, 1939, Serial No;251,544.

Priorto my invention weather or draft strips have usually been attachedto the body by means of staples, or small fasteners, and such fasten-'ing means have been found to be objectionable,

as they frequently permitted water to enter the interior of the body,thereby causing damage to the upholstery and trim.

The primary object of my invention is to provide a construction ofgarnish molding, or other body part, and a Weatherstrip, which will notrequire the use of staples, or other supplemental fastening means tosecure the strip in position,

and which will provide a water or weather tight connection between thestrip and body part. Also to provide a construction which will permitthe strip to be' quickly attached, and, when attached, will securelyhold the strip in position,

so that all possibility that the strip will become- -verse1y corrugatedsheet metal, adapted to be bent in any direction to conform to the shapeof the rib and to be interengaged therewith by pressing the strip ontothe rib, so that the strip will be securely attached to the rib and anair and water tight joint will be provided therebetween.

For a more complete disclosure of the specific construction which Iemploy, reference is made to the following specification, in connectionwith the accompanying drawing in which:

Fig. 1 is a side elevation of a section of a garnish molding containingan embodiment of my invention.

Fig: 2 is a combined sectional and perspective view'of one form ofweather strip which I may employ.

Fig. 3 is a detail perspective view of the weather Fig. 2. a

Fig. 4 is a sectional view at line 4-4 of Fig. 1.

Fig. 5 is a similar view illustrating a modification.

In the drawing a section of a garnish molding a is indicated which isformed of sheet metal by means of dies and according to one form of myinvention, when the molding, or other part is formed, a rib b is formedthereon, which is located in the surface portion which is to be engagedby the window glass, or to which the weather strip is to be applied.Said rib is of dovetail formation, as its sides are slightly inclinedinward from the top of the rib, as shown in Fig. 4.

I further provide a weather strip which comprises a core consisting of astrip of thin, corrugated, slightly resilient sheet metal, thecorrugations in which extend transversely from edge to edge of thestrip, as shown on a greatly enlarged scale in Fig. 3, and are arrangedclosely together as shown, said strip being bent transversely in channelform, providing a longitudinal middle portion 0 and two side portions 0,of equal width, the width of said middle portion and said side portionsinternally corresponding to the width of the top portion of the rib 'band to the height of its sides, respectively. The sides of the core alsoextend at a slight convergence from the middle portion, as shown inFigs. 2 and 3.

Said core is covered with a textile fabric d, which is adhesivelyconnected thereto and extends transversely from within the sides ofthecore about the outer sides and middle thereof. The middle portion of thefabric is provided with a cushioning pile e, which is interwoventherein,

or is otherwise secured thereto, and which extends for the length of thecore and the width of its top portion, as shown in Fig. 2

The weather strip, as thus constructed, is forced onto the rib b, asshown in Figs. 1 and i, the sides of the core 0 being sprung apartslightly by this operation, so that when the middle portion of the coreis pressed against the top strip core employed in the strip disclosed inof the rib, the sides of the core will springtowards each other andfirmly engage the sides of the rib, and, as the sides of the latter areslightly inclined inward, the weather strip will become securelyconnected to the body part, as shown in Fig.4, and'a water tight jointwill be provided. It will be understood that if a window glass is to becushioned, the glass will be located between the cushioning pile on twoad- .iacently disposed moldings. Also that if the molding and the ribwhich is formed thereon, is

or curved formation, the strip be readily bent in any directioncorrespondingly.

In Fi 5 a slightly modified form oi attaching rib for he body member isillustrated together with a correspondingly modified form of core forthe weather strip.

In this form the body a is formed to provide a rib in having atransversely projecting portion i at one side and an inwardly inclinedside porwith, and cushioning means on the outer side of the middleportion or said core.

2. In combination with a body member having anelongated rib on the faceside thereof, a weather strip havinga U-form core or transverselycorrugated sheet metal fitted about said rib and in pressure engagementwith the outer side walls thereof by the inherent resiliency of thecore, a fabric covering on said core, and cushioning means on saidcovering arranged on the outerside of the middle portion of said I 7core.

outer side of the core onto the inner sides of its portions m and n.

In applying the weather strip, the side m is hooked onto projection iand then the strip is pressed inward, so that the side n engages theside :i of the rib. o

Consequently, when the middle portion of the core is pressed against thetop of th rib, the core and rib will be interlocked, so that the weatherstrip will be securely attached to the molding, and an air and watertight joint will be provided.

As the metal of which th core of the strip is formed is slightlyresilient, whenthe strip is pushed on to the rib, in either of the formsabove described, one or both sides of the core will yield slightly, andwhen the strip has been pushed on to its fullest extent, so that themiddle portion of the core bears against the top of the rib, the sideportion or portions will spring back to their original form and thusfirmly grip the sides of the rib.

I have also ascertained by experiment that the frictional engagement ofthe corrugated core with the rib is much greater than it would be if themetal of the core were not corrugated, so

that the fact that the core is corrugated aids materially in providing asecure attachment of the strip to the body member, and at the same timepermits bending in any direction to conform to the shape of the rib.

I claim:

1. In combination with a body member having an elongated rib on the faceside thereof, a weather strip having aU-form core of transverselycorrugated sheet metal adapted to be bent in any direction andsurrounding and fitting about said rib and frictionally engaged there-3. In combination with a body member having an elongated rib projectingtherefrom, said rib having one side inclined inward from its top, aweather strip having a generally U-shaped core of transverselycorrugated sheet metal adapted to be bent in any direction and shaped toconform to the transverse formation of said rib and fitting over andabout the outer side walls of the rib, and cushioning means on themiddle portion of the outer side of said core.

4. In combination with a body member having an elongated rib projectingtherefrom, said rib having its sides inclined inward from its top, aweather strip having a U-form core of transversely corrugated sheetmetal, the sides of said core extending convergently from its bottom andbeing fitted onto said rib and frictionally engaged therewith, andcushioning means-on the outer side of themiddle portion of said core.

5. In combination with a body member having an elongated rib-projectingtherefrom, said rib having its sides inclined inward from its top, aweather strip having a U-form core of transversely corrugated sheetmetal having convergently disposed sides conforming internally to theexterior of said rib, said core having a fabric covering extending fromthe inner sides thereof over the outer side and middle portion thereofand cushioning means connected to said having a fabric covering andcushioning material on its middle portion.
